Title: John Michael Nichols: Innovator in Memory Duplication and Device Capacity Expansion
Introduction
John Michael Nichols is a notable inventor based in Broomfield, Colorado. He has made significant contributions to the fields of memory duplication and device capacity expansion, holding a total of 2 patents. His innovative work has implications for improving processing efficiency and device connectivity.
Latest Patents
Nichols' latest patents include a "Selective Memory Duplication Arrangement" and an "Arrangement for Expanding the Device Capacity of a Bus." The first patent describes an active-standby dual processor that performs selective memory duplication through hardware and the operating system. It utilizes a page table that stores a shadowing flag for each memory page, indicating whether the corresponding page is shadowed. This arrangement allows the operating system to manage memory allocation effectively, ensuring that writes to memory are replicated on a standby processor when necessary.
The second patent outlines a system that enables banks of duplicated active devices to connect to a SCSI bus while sharing device IDs. This arrangement allows multiple hosts to share the SCSI bus and connected active devices, enhancing the overall efficiency of device communication. Tri-state buffers are employed to manage the interface between host adapters and device banks, ensuring that only one host and one bank of devices are active at any given time.
